i have just configured PBR on a srx210 using Firewall filter.
The goal was to redirect FTP traffic to isp1 and other traffic to isp2.
Now what i just want to achieve is resiliency : when isp1 is down ftp traffic will still transit using isp2 and the same for the other traffic when isp2 is down.
Other question : How to implement Source based routing ?

All that you need is a way to make the routes to isp1 inactives when it is not ready to handle traffic. The same for isp2
The PBR won't send any traffic through inactive routes.
There are some references on how to achieve this with event-scripts & RPM (track-ip behavior)

i will look at that as i am not very "fluent" on junos or maybe do you have a set of commands to do that....
any suugestion for source based routing? i see that i can enable source routing on the routing instance then what must i do?

Hi All I;m also struggling abit with the Srx Gateways , is there any documentation or examples for a PBR setup.
I'm trying to create a filter with destinations port 80 to go to a diffrent next hop but there is no next hop option on the filter actions.
How would I do that ?

you have to create a forwarding type Routing Instance ( where you will add a static route for 0.0.0.0/0 and the next-hop for your router ) and the action filter have to be routing-instance where you will specify the routing instance name that you created early.
let me know if it helps ....

Ah ok thats perfect , so for my setup I'll have three routing instanaces.
Main Mpls Router
Backup ADSL Link
But then which way is the best way to failover between the routing instances bfd or periodic events ?
Becuase I want to push al web traffic ovewr the adsl and rest via the main link with qos and the nfailover vice versa between both.
But I see I get route loop errors when I try to route between the instances , so then what instance-type did you use ?

there is an example described in here :
hope this'll help.
